Question

A team of researchers analyzed the meat from each in a sample of 18 "red snapper" fish fillets purchased from vendors across a region in an effort estimate the true proportion of fillets that are really red snapper DNA tests revealed that 6 of the 18 filets or 33%) were not red snapper but the cheaper look al keva ety of fish Complete parts a through d a. Identify the parameter of interest to the researchers The parameter of interest is p, the true proportion of fish fillets that are actually red snapper. b. Explain why a large-sample confidence interval is inappropriate to apply in this study. Choose the correct answer below. A. It is inappropriate because the sampling distribution is approximately normal O B It is inappropriate because either the number of successes in the sample or the nu er of a ures in the sample is greater than or equal yC. It is inappropriate because either the number of successes in the sample or the number of failures in the sample is less than 15 5 D. It is inappropriate because the expected probability of success is 0.33. C. Construct a 90% confidence interval for the parameter of interest using Wilson's adjustment. The 90% confidence interval is 0.468. 0.805 (Round to three decimal places as needed.) d. Give a practical interpretation of the confidence interval. With | % confidence, the interval found in part c contains the true value of

Explanation / Answer

Part d)With 90% confidence the interval found in part c contains true value of proportion.

Note: since question is posted saying correct answers are given, I have done part d only If you want me to check all parts please mention it.
